1 '0 all whom it may concern Be it known that we, SAM Grr GIvENs and HENRY Lewis, citizens of the United States, residing at Paducah and New Liberty, respectively, in the counties of Me- Cracken and Pope and States of Kentucky and Illinois, have invented a new and useful Stovepipe-Fastener, of which the following is a specification.

The invention relates to improvements in stove pipe fasteners.

The object of the present invention is to improve the construction of stove pipe fastoners, and to provide simple, efiicient and comparatively inexpensive means for securing a stove pipe in a stove pipe opening of a chimney or flue and of obviating the necessity of wiring the stove pipe to the adjacent wall and marring or otherwise disfiguring the same.

Nith this object in view, the invention consists in the construction and novel combination. of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing :Figure 1 is a vertical longitudinal sectional. view of a stove pipe, provided with a stove pipe fastener, constructed in accordance with this invention. Fig. 2 is an end elevation of the inner end of the horizontal pipe and the thimble with which the same is interlocked. Fig. 3 is a vertical longitudinal sectional view of the elbow and the adjacent portions of the vertical and horizontal pipes, the cleaner being arranged for operation within the vertical pipe. Fig. 4': is a transverse sectional view of the thimble. Fig. 5 is a perspective view of the stove pipe. Fig. 6 is an enlarged sectional view of the cleaner, illustrating the construction of the disk and the manner of connecting the coiled spring with the same and with the operating rod.

Like numerals of reference designate corresponding parts in all the figures of the drawing.

In the accompanying in which is illustrated the preferred embodiment of the in:

vention, 1 designates a stove pipe consisting of an upright pipe 2, a horizontal pipe 3 and a connecting elbow 4. The stove pipe may be composed of any number of sections, and the upright pipe is designed to be connected with a stove in the usual manner. The horizontal pipe 3 extends through a thimble 5 and projects into the chimney or flue 6. The extension or projecting portion 7 of the horizontal pipe is provided at the top with an opening 8 and portions of the metal cut to form the opening 8 are bent outwardly at opposite sides of the stove pipe to form horizontal flanges 9 for engaging the inner end of the thimble 5. The thimble 5, which is arranged within and forms a lining for the stove pipe opening of the chimney or flue, is provided at its ends with flanges 11 and it has opposite longitudinal ribs or enlargements 12, provided. with grooves or ways 13, adapted to per mit the projecting flanges 9 to be passed through the thimble and engaged with. the inner end thereof. The grooves 13 of the ribs or projecting portions 12 are arranged at diametrically opposite points, and are preferably located at the upper and lower portions 01 the thimblc in a diagonal or inclined position with relation to each other to permit the flanges 9 after being passed through the grooves 13 to be turned to a horizontal position out of register with the grooves 13, whereby the horizontal pipe 3 will be securely fastened in the stove pipe opening of the chimney or flue 6. The flanges 11 at the inner and outer ends of the thimble engage the wall 14: of the chimney or flue, as clearly illustrated in Fig. 1 of the drawing. The horizontal pipe 3 is also provided at its inner end with inwardly extending transversely disposed lugs or projections 15, arranged to form stops for limiting the inward movement of a cleaner disk 16 to prevent the same from being moved inwardly beyond the inner end of the horizontal pipe 3.

The cleaner disk or head 16, which is coneavo-convex or cup-shaped, is preferably composed of two sheets of metal and an interposed lining 17 of asbestos, which forms a cushion and which also tends to prevent the disks from burning out. The concavoconvex disk may consist of a single thickness of metal and be provided at the concave face thereof with the asbestos lining if desired. The concavo-convex cleaner disk 16 presents a convex face to the front to enable it to be readily drawn over the ends of the pipe sections and to prevent it from catching on such obstructions. The operating rod, which is connected with the concavo-convex disk 16 by the means hereinafter described, extends through a perforation 21 of the slide 22, and it is equipped at its outer end with a suitable handle 23, and is provided at a point intermediate of its ends with a joint 24:, having a pivot and adapted to permit the inner and outer portions of the operating rod to be arranged at an angle-to each other to enable the device to adjust itself to elbows having different angles, and also to permit the cleaner to be drawn outward to its full extent when operating near another wall. lVhen the space is too small to permit the operating rod to be drawn out in a straight position, the rod may be partially withdrawn and broken or swung downward at the joint to enable the inner portion of the rod to be drawn outward without contacting with the said wall. The handle 23 is in the form of a loop, but any construction of handle may of course be employed. The operating rod is provided at its inner end with a highly resilient portion 25, preferably consisting of a coiled spring and designed to be employed in a stove pipe having crooked elbows, and adapted to be flexed to permit the cleaner disk to adjust itself to the same.

lVhen the cleaner disk is arranged at the inner portion of the horizontal pipe 3, as illustrated in full lines in Fig. 1 of the drawing, a free draft through the stove pipe is afforded, and when it is desired to check the draft through the stove pipe, the cleaner disk is drawn outward to the dotted position illustrated in Fig. 1 of the drawing. The cleaner consisting of the disk and the operating rod is adapted to be drawn out wardly and forwardly in the horizontal pipe 3 to clean the same, and when it is desired to clean the upright pipe, the cleaner disk is brought to a position within the elbow and the operating rod is swung upward to arrange it in a vertical position, as illustrated in Fig. 3 of the drawing. To permit this operation, the elbow is provided with an enlarged circular concavo-convex outer portion 26.provided with a slot 27 and having guides or ways 28 at opposite sides thereof to receive the said slide 22. The guides or ways 28, which are arranged in parallelism, are arcuate and extend from the bottom to the top of the concavo-convex enlargement 26, and preferably consist of angle strips or pieces approximately L-shaped in cross section to form grooves to receive the side edges of the slide 22. The slide 22, which is curved to conform to the configuration of the ways and the enlarged portion 26, is

slidable upwardly and downwardly in the grooves or ways to permit the cleaner to be arranged in either the vertical pipe 2 or the horizontal pipe 8. The slide is of sufficient length to cover or close the slot or opening 27 in any adjustment of the cleaner, and it prevents smoke or soot escaping into the room during the operation of the cleaner.

The inner end of the coiled spring 25 is connected with the reduced end 29 of the inner portion of the operating rod 20 by means of a key 30, or other suitable fastening device, which pierces the reduced end 29 and extends through the coils of the spring. The reduced end 29 forms a shoulder against which the adjacent end of the spring abuts, and which prevents the separation of the end coils from the key. The outer end of the spring 25 is connected with the concavo-convex disk by means of a pin 31, piercing the metallic plies or sheetsand the interposed lining of the concavo-convex disk at the center thereof, and provided at its outer end with a head and extending into the outer end of the coiled spring, which is secured to the pin by means of a key 32, or other suitable fastening device. The key 32 pierces the pin and passes between the coils at the outer end of the spring. The terminals of the spring may be connected with the operating rod and the cleaner disk in any other suitable manner, and the resilient section or portion of the operating rod may be formed by any other suitable means, which will permit a flexing of the rod. No claim is made in the present application to the stove pipe cleaner and damper.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent, is

1. A device of the class described including a horizontal stove pipe provided with a terminal extending portion adapted to project into a chimney or flue beyond the wall thereof and having an opening in the top located beyond the wall of the chimney or flue, said terminal portion being also provided with projecting flanges located at opposite sides of the opening, and a thimble provided with opposite grooves extending the entire length of the thimble and adapted to permit the flanges to be passed through the thimble into the chimney or flue for holding the stove pipe in its projecting position.

2. A device of the class described including a thimble provided with opposite grooves extending the entire length of the thimble, and a horizontal stove pipe provided with a projecting portion having an opening and provided at opposite sides thereof with flanges extendingthe length of the opening and formed by portions of metal gaging the latter to hold the stove pipe in 15 its projecting position.

In testimony, that we claim the foregoing as our own, we have hereto afliXed our signatures in the presence of two Witnesses.
